Bioavailability of sorbed 3-chlorodibenzofuran.

Applied and Environmental Microbiology
Hauke Harms, A J Zehnder

Abstract

One of the main factors impeding the bioremediation of polluted soils, sediments, and aquifers is the low bioavailability of chemicals which are sorbed by organic matter. To obtain more insight into the factors that control the degradation of sorbed compounds, we used a defined model system in which 3-chlorodibenzofuran (3CDF) was the organic contaminant, porous Teflon granules were the sorbent, and Sphingomonas sp. strain HH19k was the test organism. The sorption of 3CDF to Teflon reached equilibrium within 150 min. The curved shape of the sorption isotherm, the extent of sorption, and the desorption kinetics suggested that there was a surface interaction (adsorption) between 3CDF and Teflon which took place mainly inside the pores of the granules. The kinetics of desorption could be ascribed to sorption-retarded radial diffusion inside the granules since the desorption rate not only was correlated with the sorbed-phase concentration, but also depended on the equilibration status of sorption, since (i) the high initial desorption rate sharply declined because of the depletion of 3CDF in the outermost parts of the granules, but high rates were observed again after the system had been given time to reequilibrate, and (ii) the in...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
